Gene Information

Application

Triparanol has been used to inhibit cholesterol biosynthesis in lipid rafts1. Triparanol has also been used as a 3β-hydroxysterol-Δ24-reductase inhibitor to study its effect on delayed-rectifier potassium current (Iks) channels2.

Biochem/physiol Actions

Triparanol is known to repress Hedgehog signaling in cancer cells and can also inhibit tumor growth3.
Desmosterol Delta24 (D24) reductase inhibitor.

Preparation Note

Triparanol is soluble in DMSO at 20 mg/ml and is also soluble in alcohol. It is slightly soluble in olive oil and is insoluble in water.

The tetracyclic sterol precursors, cyclolaudenol, cycloartenol and lanosterol, inhibit efficiently the tetrahymanol biosynthesis in the ciliate Tetrahymena pyriformis, as reported earlier for cholesterol and other sterols. The prokaryotic bacteriohopanetetrols have little effect, and diplopterol, another hopanoid, as well as the

Like many solid tumors, sarcomas are heterogeneous and include a small fraction of the so-called side population (SP) cells with stem-like tumor-initiating potential. Here, we report that SP cells from a soft tissue tumor of enigmatic origin termed undifferentiated pleomorphic

Lipid rafts are plasma membrane microdomains that are highly enriched with cholesterol and sphingolipids and in which various receptors and other proteins involved in signal transduction reside. In the present work, we analyzed the effect of cholesterol biosynthesis inhibition on

The relationships between the cholesterol content of the diet, plasma cholesterol concentration, cholesterol absorption, and cholesterol synthesis (measured indirectly by desmosterol suppression technique) are explored in groups of high- and low-responding rhesus monkeys fed diets containing 0.02, 0.15 and 0.75

The cell cycle is a ubiquitous, multi-step process that is essential for growth and proliferation of cells. The role of membrane lipids in cell cycle regulation is not explored well, although a large number of cytoplasmic and nuclear regulators have
